FRANK CERAR lAND JOHN OGRINC, OF BROOKLYN, NEW YORK.

RESILIENT SHOE-HEEL.

To all lwhom t may concern:

Be it known that we, (1) FRANK CERAR and (2) JOHN OGRINC, (1) a citizen of the United States of America and (2) a subject of the Emperor of Austria, (having declared his intention to become a citizen of the United States,) residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Resilient Shoe-Heels, of

' which the following is a specification.

This invention relates to certain new and. useful improvements 1n `resilient shoe heels.

The primary object of the invention is the provision of a heel for boots and shoes adapted for imparting resiliency thereto for ease in walking, a suitable adjustable tensioning means being arranged.

A further object of the device is the provision of a shoe heel having an adjustable mechanical spring member obscured from view in such a manner as to present the ex ternal appearance of the usual shoe heel.

A still further object of the invention is the provision of a shoe heel that is easy and inexpensive to manufacture and arranges a regulated resiliency for the heel portion of a shoe, the device being` easily assembled and positioned upon a shoe as well as disassembled for purposes of repair when required.

In the drawing forming a part of this application and in which like reference characters refer to corresponding parts throughout the several views,

Figure 1 is a central longitudinal sectional view through the device arranged upon a shoe,

Figs. 2, 3 and 4 are transverse sectional views taken respectively upon lines II-II, III-III and IV`IV of Fig. 1,

Fig. 5 is a similar sectional view of a for'm of the device, arranged for mens shoes and Figs. 6V and 7 are sectional views taken upon line VI-VI and VII-VII of Fig. 5.

Referring more in detail to the drawing,

a shoe 10 is illustrated having the usual heel portion 14 and is secured 4to the latter by screws 16 passing through the outer sole 11 from the interior of the shoe 10 and threaded into bosses 17 ofthe plate 15,

Specification of Letters Patent.

Patented Apr. 2, 1918;

Application led November 17, 1917. Serial No. 202,464.

.A tubular depending portion 18 is provlded on the plate 15, open at both ends but having a transverse partition 19 arranged parallel to the tread of a heel 13. A 'bushing 20 is arranged within the tube 18 while a sleeve 21 telescopes within the bushing 20 and is adapted to slide longitudinally thereof. A stop-key 22 is provided upon a strip 23, the said Ikey being arranged through al1n1ng openings 24 and 25 in the tube 18 and bushing 20 respectively, while the key also extends within a longitudinal slot 26 in the sleeve 21 for limiting the relative movement between the said sleeve'and bushing.

An annular flange 27 is arranged at the free bottom end of the sleeve 21 adapted to receive a tread plate 28 and a tread surface or block 29 secured to the lower face thereof by means of screws 30. A flexible covering 31 preferably formed of leather similar to the construction of the shoe 10, is secured around the flange 27 and the plate 15, com- ,pletely inclosing the heel spring mechanism and held in place at its upper end between the plate 15 and the sole portion 14 and at its lower end between the flange 27 and the tread-plate 28.

A helical spring32 is centrally arranged within the bushing 20 between the partition 19 and the bottom 33 of the sleeve 21, whereby resiliency is given to the structure. A hollow post 34 is arranged'upon said bottom 33 encircled by the spring 32 While a tensioning screw 35 is swiveled through the top 36 of the post 34 and centrally threaded through the partition 19. The chamber 37 in the upper end of the'tube 18 above the partition 19 accommodates the free end of the screw 35 and it will be understood that 95 by moving the screw upwardly, in its threaded engagement with the partition 19, by `turning the head 38 of the screw, the tension of the spring 32, will be increased while the lowering of the screw by reversing the direction of rotation, thereof, would decrease the tension upon the said spring.

A dished spring washer 39 surrounds the sleeve 21 and is mounted upon the flange 27 so that any excessive upward movement of the said sleeve will seat the tube 18 and bushing 20 upon the washer 39, thereby absorbing the shock of any excess1ve load such as that exerted by jumping, the washer 39 being also serviceable in the event of the breaking of the spring 32. This .form of heel 13 is especially adapted for womens shoes. j

ln Figs. 5, 6 and 7 a modified form of spring heel 40 is provided arranged upon a shoe 41 having a sole 42, the same consisting of a plate 43 secured to the sole 42 by screws 44 and having a tread-member 45 resiliently spaced beneath the plate 43 by a plurality of helical springs 46. The springs 46 are positioned in circular sockets 47 arranged in the adjacent faces of the plate 43 and tread-member 45 while a leather covering 48 incloses the mechanism being secured at its upper end between the sole 42 and the plate 43 and at its lower end between the tread-member 45 and a disk 49 of thetread block 50, securing screws 51 being arranged between the members 49, 50 and 45.

Limiting links 52 are arranged centrally of the springs 46 with their lower ends arranged with cross-pins 53 extending therethrough carried by the tread-member 45 within openings 54 arranged in the said tread-member. The upper ends of the links 52 are provided with similar pins 55 transversely -carried by sleeves 56 threaded in openings 57 in the plate 43. It will be seen that the shoe 41 is cushioned by means of the springs 46 while their tension is initially set and determined by positioning the sleeves 56, the entire structure possessing great strength and durability.

What we claim as new is 1. A spring heel comprising an attaching plate, having a depending tube, a partition arranged intermediate the-ends of the tube, forming an upper chamber therein, a sleeve telescoping within the tube, a spring positioned between the sleeve and' partition, a tensioning screw for the spring having journaled connection with the sleeve andadjustably threaded through the partition projecting into the said chamber, and a treadmember upon the lower end of the sleeve.

2. A spring heel comprising an attaching memes plate, having a de ending tube, a partition arranged intermediate the ends of the tube, forming an upper chamber therein, a sleeve telescoping within the tube, a spring positioned between the `sleeve and partition, a tensioning screw for the spring havingjournaled connection with the sleeve and adjustably threaded through the partition projecting into the. said chamber, the said tube having an opening therethrough, and the sleeve having a longitudinal slot adjacent the openingand of greater length than the opening, a movement limiting key carriedk by the tube, extending through the opening thereof and into the said slot, a-ange upon the lower end of the sleeve, and a treadmember secured to the said flange.

3. A spring heel lcomprising an attaching plate, having a de ending tube, a partition arranged intermediate the ends of the tube,

forming an upper chamber therein, a sleeve telescoping within lthe tube, a spring positioned between the sleeve and partition, a tensioning screw for the spring having journaled connection with the sleeve and adend secured between the plate and sole and its lower end retained between the said flange and tread-member.

In testimony whereof we aHiX our signatures.
